We do still use CarpetRegrid at GT but do not maintain it (since it is 
part of Carpet). Since CarpetRegrid2 can do (almost) everything that we 
need of CarpetRegrid we will likely transition to Regrid2 when we 
transition to Carpet/Hg (though Tanja will have to decide on this). At 
that point we will likely start working around things that CarpetRegrid 
did and Regrid2 does no longer do (eg. easy steering of parameters when 
recovering). On the other hand having full and easy to use AMR in 
Regrid2 is very likely worth any associated pain of transitioning to a 
new thorn :-)
